On the Buchstaber invariant of simple convex 3-polytopes
In this paper the author gives a method of constructing characteristic matrices, and uses it to determine the Buchstaber invariants of all simple convex 3-polytopes, which imply that each simple convex 3-polytope admits a characteristic function. As a further application of the method, the author also gives a simple new proof of five-color theorem.
